Fry the onions in a little oil in a coated pan until translucent, then add the mushrooms and carrots and fry with them. Now mix in the ajvar. If it is too thick, add a little water. Mix in the kidney beans and continue to simmer. Mix in the cooked rice, then add the corn and mix everything together. Season with salt and Tabasco, stir and serve.
